排出代謝產(chǎn)物,幫助保持水鹽平衡,使人體內(nèi)環(huán)境保持動態(tài)平衡.

人體在維持生存，就要有新陳代謝，也就是吐故納新。人們每個攝入的食物當(dāng)中有不少有害成份，這些有害成份和營養(yǎng)成份一起被腸道吸收，進(jìn)入腸系膜靜脈，腸系膜靜脈匯總到門靜脈進(jìn)入肝臟，對各種成份進(jìn)行加工處理，通過肝細(xì)胞當(dāng)中各種酶的作用將營養(yǎng)成份進(jìn)一步裂解成人體細(xì)胞可以吸收利用的小分子，在這個過程中又會產(chǎn)生一些有害裂解產(chǎn)物。這些有害物質(zhì)如果輸送到人體各個細(xì)胞，對這此細(xì)胞是有害的。因此，必須有一個清除機(jī)制，這就是腎臟。腎臟就像兩個大篩子，不停地往排出有害小分子物質(zhì)，同時又不能讓血細(xì)胞和血中的營養(yǎng)物質(zhì)流失。通過腎臟的篩眼出來的物質(zhì)除了有害物質(zhì)還有水，腎的遠(yuǎn)端小管又把他們吸收回去再利用，這樣，篩出的初尿就逐漸濃縮成了尿液。如果腎功能損傷，無法向外排出有害物質(zhì)，這些有害物質(zhì)就會在體內(nèi)堆積起來，毒害全身的細(xì)胞，這就是尿毒癥。尿毒癥病人必須每隔一段時間，一周兩三次吧，通過血液透析機(jī)把血液中的有毒物質(zhì)過濾出去，他們才能活下來?！　∨拍蚴菫榱伺诺舳嘤嗟乃?，尿素，多余的鈣和磷，以及各種被腎過濾的毒素，比如農(nóng)藥殘余物。其中尿素是最主要的，人和植物不一樣，沒有氨基酸庫，不能儲存作為能源之用的蛋白質(zhì)或氨基酸。蛋白質(zhì)經(jīng)消化吸收后，除了供生長之外，多余的蛋白質(zhì)必須放也氨基然后轉(zhuǎn)化為糖原或脂肪進(jìn)行儲存，這個過程必須放出氨基，也就是放出含氮廢物，這些含氮廢物經(jīng)肝等器官轉(zhuǎn)化成尿素后經(jīng)腎過濾，溶于水后排出就形成尿。也不是所有的動物都要排尿，有些爬行動物為了節(jié)水，就把含氮廢物加功成不溶于水的尿酸排出，人要是產(chǎn)生尿酸就會引發(fā)腎結(jié)石。

6，生物急求排泄的意義

簡單說就是能促進(jìn)新陳代謝，排除代謝廢物和對個體有毒的物質(zhì)。

生物代謝產(chǎn)生的廢物必須排出體外，否則將破壞內(nèi)環(huán)境的穩(wěn)定，導(dǎo)致中毒。如人患腎炎，排尿發(fā)生障礙，就出現(xiàn)尿中毒的癥狀。排泄的對象是細(xì)胞代謝廢物，排泄過程一般都是耗能的。是由排泄器官完成的，人體過量的Ca2+和Fe2+是隨糞便排出的，而這些離子以及細(xì)胞一些分泌物都是細(xì)胞代謝過程產(chǎn)生的，嚴(yán)格地說，這應(yīng)屬排泄而不是排遺。同理，肺排出CO2，肝排除膽汁，也都應(yīng)屬于排泄。排泄排泄的過程同時也是保持體液穩(wěn)定的過程。飯菜咸了要多喝水，結(jié)果尿多，而排尿的結(jié)果既排除了過多的水，也排除了過多的鹽。動物的代謝廢物主要是細(xì)胞呼吸產(chǎn)生的CO2和蛋白質(zhì)等分子分解產(chǎn)生的含氮廢物，如NH3、尿素、尿酸等。呼吸系統(tǒng)負(fù)責(zé)排出CO2。排泄系統(tǒng)則是排除含氮廢物。在于大多哺乳類來說，它們經(jīng)兩種主要的途徑進(jìn)行排泄作用。其之一為腎臟產(chǎn)生尿液(見泌尿系統(tǒng))，經(jīng)排尿作用排出體外；另外一種為呼吸作用所產(chǎn)生的二氧化碳，經(jīng)肺部呼出體外。排尿作用受激素抗利尿激素所控制，此激素能增加遠(yuǎn)曲小管重吸收水的能力，并透過改變其自身濃度來控制排尿量，它是由腦小丘制造，并于腦下垂體儲存及分泌。排汗是另一種排泄作用，它可以排走水分及鹽，但其實(shí)這個機(jī)制的主要目的是降溫。狗只并沒有皮膚排排泄汗機(jī)制。人類的主要排泄器官是腎以及輔助的泌尿器－用以排出尿液；以及大腸－用以排出固體的廢物。皮膚及肺部皆有排泄的功能：皮膚以流汗的方式排走水分及鹽，肺部則排出水蒸氣及二氧化碳。其中二氧化碳為人體最主要的代謝廢物。

research purposescommunity health service as the base of urban health care system in china is the mostimportant access to enhance the implementation of reform on the urban system. communityhealth service in china has developed remarkably under the promotion of central governmentsince 1997, but the quality and speed of its development is still much more below than theexpectation of the society. one reason which could be applied to explore it is that there havebeen still some uncertainties concerning its key policy issues on systematical framework oncommunity health service organizations. or the problem could be concluded as whom among theprivate or public organizations can provide community health service much better concerningfunction, quality, respect to community public benefit, and efficiency? could the private sectorsplay a leading role in promoting community service development in china?just as the new health reform has started recently in china, to find the essential charactersof...更多 private community health service organizations through a well-designed comprehensive andsystematic study, which is based on its performance to public well-being, would facilitate policyimprovement and implementation on community health service development in china.this study on private community health service organizations in the key 28 cities selectedby the ministry of health is an in-depth analysis. it includes the basic infrastructure, equipment,policy implementation, financial revenues and expenditures, human resources, service provisionand relative efficiency of service provision compared to community health service agencies runby public or enterprises. except comparing according to the distribution of private communityhealth agencies in eastern, central and western part of china which is aimed to explore thedifference in development process across region, some in-depth interviews with experts,government officers, health professionals, individuals who run private community healthorganization as well as community residents and field investigation to some private communityhealth service organizations have also been carried out. it is great significance that the currentdevelopment status of private community service organizations in china and its essential characters have emerged through the research which would provides a solid foundation in theoryand methodology for formulating relevant policies for the future development of communityhealth service in china.research methodsin this study, the literature review, field investigation, experts discussion, the descriptiveanalysis and hypothesis testing methods were used. in data analysis and processing, we haveused statistical description, chi-square test and dea methods.research contentsfor evaluation on the development status of private community health serviceorganizations, this study has focused on important aspect of all community health serviceorganizations in the key 28 cities. it included: (1) infrastructures status and implementation ofrelevant policies of the investigated private community health service organizations, in order toexplore the internal and external environment; (2) the financial revenues and expenditures:including revenues, expenditures and the balance of payments; (3) human resources: thecomposition of qualifications, titles, professions and personnel training; (4)service provision:mainly included prevention, health care, medical care, family planning, rehabilitation, andhealth education.; (5) the relative efficiency of services: mainly focused on the key cities.research resultsthe study has shown that private community health service organizations had some effecton making up for the lack of health resources, promoting the establishment of communityhealth services organizations, facilitating patients to get medical treatment at community as wellas had some influence on reform of public community health service facilities. the study hasalso shown some challenges to private community health service organizations: (1) it isdifficult for it to make clinical decision primarily according to the benefit of client, for instance,induced utilization on drugs and mainline are too often to be observed; (2) it is hard for it toimplement qualified public health intervenes due to difference on quantity of compensation frompublic finance; (3) it is hard sometime for it to provide equal qualified service infrastructure for its clients compared to other communities in the same city; (4) sometime it is too often of aprivate community health service agency closes its operation in a community due to transfer itsfund to other issue. (5) it is not unusual that the internal management is poor and not wellregulated in some private community health service organizations, for instance, though theservice efficiency of the private community health service centers in 77.78 percent of the keycities are dea effective relatively, while the private community health service stations weredea effective relatively in only 22.73 percent of the key cities; (6) there are some weakness onexterior surveillance as well as in policy implementation which is designed to help the service.people can easily make their own judgment on the essential character of private communityhealth service organizations at current period in china due to the information provided by theresearch.policy suggestionsin view of the evaluation results, this study proposed the following policyrecommendations: (1) community health service organizations run by public should play theleading role in community health development in china in order to protect the benefit of publiceven from the systematical framework aspect. (2) the government should strengthensupervision and management for private community health service organizations; (3) privatecommunity health service organizations should focus on improvement of its internalmanagement, especially focused on quality of medical care services as well as honesty to itsclient; (4)the government should direct and help private community health service organizationsin providing public health and medical care service properly, especially through implementingrelevant policy supporting that includes policy of finance, policy of price control, policy ofrevenue, policy of social medical insurance, policy of health service administration, etc. (5)the government should pay much more attention on promoting the development of the wholecommunity health service system in the country, especially helping the central and western partof china, enhancing the reform of operational mechanism as well as improving training forcommunity health professionals. the innovation of the study1. we conducted a comprehensive, systematic, objective and in-depth research about thedevelopment of pchs institutions for the first time.2. we compared pchs and the chs that belong to government or the affiliated medicalinstitutions and enterprises firstly, in order to disclose the main strengths and weaknesses ofpchs.the limitations and the further study suggestions1. as a result of restrictions on raw data, we failed to conduct the analysis about thecommunity health service quality and user satisfaction, which will be the subject of researchfocus of the next step.2. due to the shorter time span of the database, we could not make a vertical comparison bydifferent years
